This seems curious. I took my Plus 2 S engine apart for evaluation and checked valve lash. The intake measured .007 on all 4 which seemed good to me. But when I measured the exhaust I found they were consistent but at .014. (Spec is .005 to .007 for intake and .009 to ,011 for exhaust).
The consistency is the curious part, it doesn't seem that they would wear that evenly. This is my first lotus twin cam so perhaps they do. Otherwise is there a reason someone might have purposely increase the gap on the exhaust valves?
My plan is to re-shim the exhaust ones at .010 and leave the intakes as is.
